nForce4? Driver? Mobo? Problem with Flatout 1

[jamonox]

Epox EP9-NPA + Ultra, nForce4, AMD X2 4200+, Geforce 8600GTS, Realtek PCI NIC. Fixed IPs, starting from 123.1.1.1.
When starting a multiplayer session both can usually choose a car, but latest when the run is started "Epox" either freezes (if it is slave) or the other machine gives "Connection to host lost" (if it is slave). The master machine (which ever it is) continues normally. Official patch installed.

We proved this to be somehow HW /driver related: two separate XP installations both w latest nVidia drivers (6.86 and 169.21). Firewall and antivirus down. An extra Realtek NIC installed to PCI slot. Tried a straight crossconnected cable between the machines. Networking is otherwise ok, we can move files from one machine to another. Put any other machine (we have several) instead "Epox", game works normally.

We have from first publish played Flatout 1 with several different compositions, all self built. First time this occurs. Any ideas?

Finally, I have solved the problem. It was driver related yes, but nForce or NIC driver NO.

I managed to get another nForce4 MB machine, which worked OK w the games. Examining closely only one thing was relevantly different: the Epox machine did NOT have AMD driver installed, the other one did. Copied it, installed and everything started working.

The biggest reason for not finding this earlier, is that Epox has not listed any downloadable drivers for this MB at their site, oddly enough.

The driver I have now used came from Asus´s site and is pretty old, I guess you might find a newer one from here:
